Most people don't know the difference between a 34.5kV 600amp 25KAIC CAPACITOR switcher and a 12kV 4MVAR metal enclosure with breaker and reactor.  

Include inspection of the housing vault enclosure.

What's absurd and scary is that in another building of mine, with valid state and city inspections before and after purchase, has a basement stair enclosure and door of thin wood alone!

My handyman has never done anything like this and is nervous about damaging the new FG enclosure.

Based on the ARV I'd tile, surround enclosure or one piece tub shower if possible.  

Built in wine fridge.Open floor plansHigh ceilingslarge master bath with separate tub & shower, split vanities (do "his" higher) and make sure the shower is decent sized...frameless glass enclosures are nice.  

Keep the colors light and bright and glass enclosures and it will appear bigger.  

Like @JDMartin said, You can replace the enclosure by cutting that out in pieces and then installing a new iron tub and tiling the wall surround.

If it's a "true" 1,700, no garage conversion or patio enclosure, you might get close. 

Another idea I had was to put it into a "rack cabinet enclosure" (Amazon) and then somehow bolt that down onto a shelf or cabinet.But then the router/modem would be visible...
